Datum Axis Features
The properties of the Datum Axis feature are defined in the pfcDatumAxisFeat data object.
Properties Introduced:
The properties of the pfcDatumAxisFeat object are described as follows:
• Constraints—Specifies a collection of constraints given by the pfcDatumAxisConstraint object. The property pfcDatumAxisFeat.Constraints obtains the collection of constraints applied to the Datum Axis feature.
This object contains the following attributes:
◦ ConstraintType—Specifies the type of constraint in terms of the pfcDatumAxisConstraintType enumerated type. The constraint type determines the type of datum axis. The constraint types are:
▪ DTMAXIS_NORMAL—Normal datum constraint.
▪ DTMAXIS_THRU—Through datum constraint.
▪ DTMAXIS_TANGENT—Tangent datum constraint.
▪ DTMAXIS_CENTER—Center datum constraint.
Use the property pfcDatumAxisConstraint.ConstraintType to get the constraint type.
◦ ConstraintRef—Reference selection for the constraint. Use the property pfcDatumAxisConstraint.ConstraintRef to get the reference selection handle.
• DimConstraints—Collection of dimension constraints given by the pfcDatumAxisDimensionConstraint object. The property pfcDatumAxisFeat.DimConstraints obtains the collection of dimension constraints applied to the Datum Axis feature.
This pfcDatumAxisDimensionConstraint object contains the following attributes:
◦ DimOffset—Offset value for the dimension constraint. Use the property pfcDatumAxisDimensionConstraint.DimOffset to get the offset value.
◦ DimRef—Reference selection for the dimension constraint. Use the property pfcDatumAxisDimensionConstraint.DimRef to get the reference selection handle.
